Allocation Aging

Last updated 30 July 2018 10:01

Because NeSI Core-h and Node-h allocations must be consumed on a use or lose basis, and to ensure users have a clear understanding of their remaining (physical) core-h allocations, NeSI ages HPC Project Allocations using the following formula:

A(t)=A(t0)–MAX(U(t), INT((t–t0)/Δn) ×A(t0)× Δn/ ΔT ))

Where:

t is the current date

t0 is the date on which the Project Allocation was available for use by the Project

U(t) is the project usage since t0

A(t) is the Allocation available on date t (therefore A(t0) is the HPC Allocation awarded to the project)
